English abstract:
In this paper we present a calculus algorithm for the study of the compressible fluidīs stationary motion through profile grids, on an axial-symmetric flow-surface, in variable thickness of stratum. We show the applicability of the boundary element method (BEM) with real values, and the possibility of solving the integral equation of the velocity potential by using the successive approximation method w.r.t. the fluidīs density and the thickness variation of fluid stratum. In our approach the derivatives of the velocity potential are calculated by employing the Lagrange interpolation formula through five points.
